xml_func.py: strip(): Added preserve param for XML functions not to remove

db_xml.py: put_table(): Handle forward pointers in translation-to-sql_gen step instead of in XML-tree-parsing step, so that special handling for structural XML functions can use the parsed tree before any sql.put_table() processing takes place

xml_dom.py: Added is_node()

sql.py: table_row_count(): Pass start=0 to mk_select() to avoid "SELECT statement missing a WHERE, LIMIT, or OFFSET clause" warnings

sql.py: put_table(): Handle unknown exceptions by returning NULL for all rows. Refactored Missing mapping for NOT NULL column handling to use new helper function remove_all_rows().

sql.py: put_table(): Assert that insert_out_pkeys and insert_in_pkeys have same row count. Assert that pkeys and in_table have same row count.

db_xml.py: put_table(): Use new sql.table_row_count()

sql.py: Added table_row_count()

db_xml.py: put_table(): Use new sql_gen.row_count

sql_gen.py: Added row_count

db_xml.py: put_table(): Count # rows and update in_row_ct_ref once all columns have been processed. Don't pass in_row_ct_ref to recursive calls because it should only be increased once.

db_xml.py: put_table(): Added in_row_ct_ref param to store the # of input rows processed. Renamed row_ct_ref param to row_ins_ct_ref to distinguish it from new in_row_ct_ref param.

sql_gen.py: MockDb.esc_name(): Don't use sql.esc_name_by_module() to avoid circular dependency on sql module

sql.py: put_table(): Factored out mk_select() calls in calls to run_query_into_pkeys() into new helper function insert_into_pkeys()

sql.py: put_table(): run_query_into_pkeys() calls use order_by=None in their select statements because there is a pkey, so order (row #) does not matter

db_xml.py: put_table(): Subset in_table if limit != None or start != 0. start param defaults to 0 again to avoid subsetting the table when starting from row 0 (with no limit).

db_xml.py: put_table(): Don't pass limit, start recursively, because the table subsetting will happen only once in the first invocation of the function. Moved limit, start params to end since they are not passed recursively. start param no longer defaults to 0 because this is not needed since sql.put_table() now sets start to 0 where needed.

sql.py: put_table(): Removed limit and start params because they were never fully implemented, and because it's simpler to just have the caller subset their input table

lists.py: Added uniqify()

sql.py: Moved mk_flatten_mapping(), flatten() to Basic queries section since they don't involve database structure info

sql.py: put_table(): Use single quotes rather than double quotes around strings where possible

schemas/functions.sql, vegbien.sql: Changed CAST-related relational functions to return NULL on data exceptions and convert the exceptions to warnings. This helps column-based import by mapping invalid values to NULL instead of aborting the whole query on the first invalid value.

sql.py: index_col(): Cache the query so it doesn't try to add an index on the same column multiple times

sql.py mk_select(), sql_gen.py Join.to_str(): Fixed bug where conditions needed to be wrapped in () before being AND-ed together to ensure the proper operator precedence

sql.py: put_table(): Add index on columns with invalid values to enable fast filtering

sql.py: Added index_col()

sql.py: put_table(): Add pkey on returned pkeys table to enable fast joins

sql.py: Added index_pkey()

sql.py: mk_update(): When running sql_gen.to_name_only_col(), check that the col's table is table

sql.py: put_table(): Renamed pkeys to insert_pkeys to distinguish them from the full set of pkeys on the input table

sql.py: put_table(): FunctionValueException: Change invalid values to NULL using UPDATE instead of filtering them out using WHERE, to avoid adding lots of conditions to the SELECT statement

sql.py: Added mk_update() and update()

sql_gen.py: Added to_name_only_col()

sql_gen.py: Added as_Value()

sql.py: mk_select(): conds: Use new sql_gen.ColValueCond instead of sql_gen.as_ValueCond(). Documented that Code and ValueCond are sql_gen objects.

sql_gen.py: Added ColValueCond

sql.py: mk_flatten_mapping(): Filter str(col) through clean_name() to remove quotes, etc.

sql.py: Added clean_name()

sql.py: put_table(): Join together input tables into new table for speed and so don't modify input if values edited

sql.py: mk_flatten_mapping(): Take as_items param to return a list of dict items instead of a dict. Sort preserve cols before other cols. flatten(): Turn on as_items so that cols list is sorted in input order, with preserve cols first. This ensures that if a pkey is provided in preserve, it will be the first col in the generated table.

sql.py: mk_flatten_mapping(), flatten(): Take list of cols to select instead of using all cols in all tables to join

sql.py: mk_flatten_mapping(), flatten(): Renamed flat_table param to into to be consistent with run_query_into() and put it first because it is the output param

sql.py: Added flatten()

sql.py: mk_flatten_mapping(): preserve Col objects will have tables changed to flat_table to work with flattened table

sql.py: mk_flatten_mapping(): Added preserve param for list of columns not to rename

sql.py: esc_name_by_module(): Support module value None, and use default module psycopg2 for it

sql.py: put_table(): Renamed *pkeys_ref to *pkeys to reflect that they are now objects rather than an array-based references

sql.py: run_query_into(): Renamed into_ref param to into to reflect that it's now an object rather than an array-based reference

sql.py: run_query_into(): Made into_ref a sql_gen.Table instead of an array containing a table name to improve flexibility and clarity

dicts.py: Added join()

sql.py: Added mk_flatten_mapping()

sql.py: put_table(): Renamed the copy of in_tables that gets modified to in_tables_, so that the original list can eventually be reused in joining together the input tables into a temp table

sql.py: run_query(): FunctionValueException: Also match "date/time field value out of range" errors

sql.py: put_table(): conds: Use a set instead of a list for faster checking of the "cond not in conds" assertion

sql.py: mk_select(): conds: Support containers of any iterable type

sql.py: put_table(): Made conds a list so that there can be multiple conditions on the same column

sql.py: mk_select(): conds is list of (key, value) tuples instead of dict (dict still supported for compatibility), so that there can be multiple conditions on the same column

sql.py: mk_select(): conds is list of (key, value) tuples instead of dict (dict still supported for compatibility), so that there can be multiple conditions on the same column

util.py: NamedTuple inherits from objects.BasicObject so that it's comparable and hashable. This fixes a bug in dicts.make_hashable() where the NamedTuple created for a dict would appear to be hashable but would always compare as unequal.

sql.py: DbConn.esc_value(): Run strings.to_unicode() on the generated string so that if it contains unescaped non-ASCII characters, these will not cause problems when concatenated with plain strings

sql.py: run_query(): FunctionValueException: Unpack match.groups() into vars to make code clearer

exc.py: str_(): Avoid traceback exception-formatting functions when possible because they escape non-ASCII characters

sql.py: get_cur_query(): If no raw query: Use strings.ustr() instead of repr() to ensure that if the exception is parsed, embedded quotes will not be double-escaped. Prefix the query by [input] to show that it's not the raw query.

sql_gen.py: Non-Code objects: str() passes informative placeholder string to self.to_str() instead of empty string

sql.py: ExceptionWithNameValue: Use repr() instead of strings.ustr() on the value

sql.py: run_query(): Exception parsing: Use non-greedy qualifier "?" in regexps wherever possible to avoid matching closing quotes later in the error message

sql_gen.py: MockDb.esc_value(): Use repr() instead of strings.ustr() so the quotes around the value are included

sql_gen.py: ValueCond and Join class hierarchies inherit from objects.BasicObject like Code does

sql.py: put_table(): ignore(): Fixed bug where value needed to be filtered through repr(). NullValueException: Fixed bug where value passed to ignore() was the string 'NULL' instead of the value None.

mappings/DwC2-VegBIEN.specimens.csv: plantname.rank: Filter through _toTaxonrank

sql.py: put_table(): ignore(): Avoid infinite loops by asserting that in_col is not in conds

objects.py: BasicObject: Fixed bug where util needed to be imported. Added eq() and hash().

strings.py: Removed no longer used DebugPrintable (that functionality is now in objects.BasicObject)

sql_gen.py: Code: Inherit from new objects.BasicObject

Added objects.py

sql.py: put_table(): Renamed log_ignore() to ignore() and factored common conds-modifying code into it

sql.py: put_table(): Moved post-insert code outside while loop because it will now always be run (there are no longer special cases where the postprocessing doesn't happen)

sql.py: put_table(): Missing mapping for NOT NULL column: Just create an empty pkeys table, since the missing rows' pkeys will be set to NULL later

sql.py: put_table(): Joining together output and input pkeys: Use new sql_gen.join_same_not_null

sql.py: put_table(): Setting missing rows' pkeys to NULL: Use new sql_gen.join_same_not_null

sql_gen.py: Join: Added join_same_not_null. to_str(): Refactored to switch order of left and right tables and cols because left_table is on the right in the comparison, and using the sides of the comparison instead of the sides of the join makes the code clearer.

sql_gen.py: Renamed join_using to join_same to reflect that it can also be used without USING

sql.py: put_table(): Set missing rows' pkeys to NULL

sql.py: put_table(): NullValueException: no mapping for missing col: Fixed bug where run_query_into_pkeys() was still using insert_joins instead of input_joins

sql_gen.py: Added MockDb. All str() methods: Use self.to_str() with mockDb.

sql_gen.py: Use db.esc_name() instead of sql.esc_name(db, ...) so passed-in db can be a mock object

sql.py: DbConn: Added esc_name()

db_xml.py: put_table(): Debug-print which columns are being put

sql.py: ConstraintException, NullValueException: Improved error messages

sql.py: put_table(): FunctionValueException: Fixed bug where out_table was still assumed to be an escaped string, but is now a Table object

sql.py: mk_select(): joins: Use new table_not_null_col() instead of pkey() to get a non-NULL column to filter out on

exc.py: add_msg(): Fixed bug where msg needed to be converted to a unicode object before appending it to another unicode object

mappings/VegX-VegBIEN.stems.csv: Fixed bug where taxonfit was named taxonFit. (This was only recently discovered because column names are now escaped, causing them not to be case-insensitive.)

sql.py: Added table_not_null_col()

sql.py: Added table_cols() and use it in pkey()

schemas/vegbien.sql, schemas/functions.sql: Relational functions: Added dummy not_null column to provide a column to use in LEFT JOIN filter-out filters

sql.py: mk_insert_select(): embeddable: Use new sql_gen.NamedTable

sql_gen.py: Added NamedTable. Table: Added to_Table().

sql_gen.py: Added section labels for each type of SQL code object

sql.py: put_table(): DuplicateKeyException: Fixed bug where dict_subset_right_join() was used instead of dict_subset(), adding spurious None values for columns in the constraint which are not in the input tables
