" History
"
" TODO
" - Jonas Enberg - if no table is found when using column completion
" look backwards to a FROM clause and find the first table
" and complete it.
"
" Version 16.0 (Dec 2015)
" - NF: If reseting the cache and table, procedure or view completion
" had been used via dbext, have dbext delete or recreate the
" dictionary so that new objects are picked up for the
" next completion.
"
" Version 15.0 (May 2013)
" - NF: Changed the SQL precached syntax items, omni_sql_precache_syntax_groups,
" to use regular expressions to pick up extended syntax group names.
" This requires an updated SyntaxComplete plugin version 13.0.
" If the required versions have not been installed, previous
" behaviour will not be impacted.
"
" Version 14.0 (Dec 2012)
" - BF: Added check for cpo
"
" Version 13.0 (Dec 2012)
" - NF: When completing column lists or drilling into a table
" and g:omni_sql_include_owner is enabled, the
" only the table name would be replaced with the column
" list instead of the table name and owner (if specified).
" - NF: When completing column lists using table aliases
" and g:omni_sql_include_owner is enabled, account
" for the owner name when looking up the table
" list instead of the table name and owner (if specified).
" - BF: When completing column lists or drilling into a table
" and g:omni_sql_include_owner is enabled, the
" column list could often not be found for the table.
" - BF: When OMNI popped up, possibly the wrong word
" would be replaced for column and column list options.
"
" Version 12.0 (Feb 2012)
" - Partial column name completion did not work when a table
" name or table alias was provided (Jonas Enberg).
" - Improved the handling of column completion. First we match any
" columns from a previous completion. If not matches are found, we
" consider the partial name to be a table or table alias for the
" query and attempt to match on it.
"
" Version 11.0 (Jan 2012)
" Added g:omni_sql_default_compl_type variable
" - You can specify which type of completion to default to
" when pressing <C-X><C-O>. The entire list of available
" choices can be found in the calls to sqlcomplete#Map in:
" ftplugin/sql.vim
"
" Version 10.0
" Updated PreCacheSyntax()
" - Now returns a List of the syntax items it finds.
" This allows other plugins / scripts to use this list for their own
" purposes. In this case XPTemplate can use them for a Choose list.
" - Verifies the parameters are the correct type and displays a
" warning if not.
" - Verifies the parameters are the correct type and displays a
" warning if not.
" Updated SQLCWarningMsg()
" - Prepends warning message with SQLComplete so you know who issued
" the warning.
" Updated SQLCErrorMsg()
" - Prepends error message with SQLComplete so you know who issued
" the error.
"
" Version 9.0 (May 2010)
" This change removes some of the support for tables with spaces in their
" names in order to simplify the regexes used to pull out query table
" aliases for more robust table name and column name code completion.
" Full support for "table names with spaces" can be added in again
" after 7.3.
"
" Version 8.0
" Incorrectly re-executed the g:ftplugin_sql_omni_key_right and g:ftplugin_sql_omni_key_left
" when drilling in and out of a column list for a table.
"
" Version 7.0 (Jan 2010)
" Better handling of object names
"
" Version 6.0 (Apr 2008)
" Supports object names with spaces "my table name"
"
" Set completion with CTRL-X CTRL-O to autoloaded function.
" This check is in place in case this script is
" sourced directly instead of using the autoload feature.
