Various SQL Utilities.

Version 2.0 requires Vim 7.

1. A SQL formatter, to make SQL statements (select, insert, update, delete...) more readable.  
2. Based on create table statements, will generate select lists for a table, as long as the definition exists in some open buffer.
3. Creates a generic procedure that will perform an insert, update, delete and select based on the definition of a table (if already open in some buffer).  The format is ANSI.
4.  Returns the column datatype definition for a specified column name (or supplied) based on the definition of a table (if already open in some buffer).

Functions:
[range]SQLUFormatter(..list..)
                                                                            
     Formats SQL statements into a easily readable form.
     Breaks keywords onto new lines.
     Forces column lists to be split over as many lines as
     necessary to fit the current textwidth of the buffer,
     so that lines do not wrap.
     If parentheses are unbalanced (ie a subselect) it will
     indent everything within the unbalanced paranthesis.
     Works for SELECT, INSERT, UPDATE, DELETE statements.

     Global variables to customization some aspects of the formatting:
     sqlutil_align_where - aligns the =, >=, <=, ...
     sqlutil_align_comma - places the column lists in select statement on new lines
     sqlutil_align_first_word - see examples

     You can change the case of the keywords while formatting.

Functions:
SQLUCreateColumnList( optional parameter )
                                                                            
     Assumes either the current file, or any other open buffer,
     has a CREATE TABLE statement in a format similar to this:
     CREATE TABLE customer (
     id INT DEFAULT AUTOINCREMENT,
     last_modified TIMESTAMP NULL,
     first_name     VARCHAR(30) NOT NULL,
     last_name VARCHAR(60) NOT NULL,
     balance         NUMERIC(10,2),
     PRIMARY KEY( id )
     );
     If you place the cursor on the word customer, then the
     unnamed buffer (also displayed by an echo statement) will
     contain:
     id, last_modified, first_name, last_name, balance
                                                                            
     Optionally, it will replace the word with the above and place
     the word in the unnamed buffer.  Calling the function with
     a parameter enables this feature.
                                                                            
     This also uses the g:sqlutil_cmd_terminator to determine when
     the create table statement ends if none of the following terms
     are found before the final );
            primary,reference,unique,check,foreign
     sqlutil_cmd defaults to ";"
                                                                            
                                                                            
Functions:
SQLUGetColumnDef( optional parameter )
SQLUGetColumnDataType( expand("<cword>"), 1 )
                                                                            
     Assumes either the current file, or any other open buffer,
     has a CREATE TABLE statement in a format similar to this:
     CREATE TABLE customer (
     id INT DEFAULT AUTOINCREMENT,
     last_modified TIMESTAMP NULL,
     first_name     VARCHAR(30) NOT NULL,
     last_name VARCHAR(60) NOT NULL,
     balance         NUMERIC(10,2),
     PRIMARY KEY( id )
     );
     If you place the cursor on the word first_name, then the
     column definition will be placed in the unnamed buffer (and also
     displayed by an echo statement).
     VARCHAR(30) NOT NULL        
                                                                            
     If the command is called as SQLUGetColumnDef( expand("<cword>"), 1 )
     or using the default mapping \scdt, just the datatype (instead
     of the column definition) will be returned.  A separate command
     SQLUGetColumnDataType has been created for this.
     VARCHAR(30)
                                                                            
                                                                            
Functions:
SQLUCreateProcedure()
                                                                            
     Assumes either the current file, or any other open buffer,
     has a CREATE TABLE statement in a format similar to this:
     CREATE TABLE customer (
     id         INT DEFAULT AUTOINCREMENT,
     last_modified   TIMESTAMP NULL,
     first_name     VARCHAR(30) NOT NULL,
     last_name VARCHAR(60) NOT NULL,
     balance         NUMERIC(10,2),
     PRIMARY KEY( id )
     );
     By calling SQLUCreateProcedure while on the name of a table
     the unnamed buffer will contain the create procedure statement
     for insert, update, delete and select statements.
     Once pasted into the buffer, unneeded functionality can be
     removed.
                                                                            
                                                                            
                                                                            
Commands:
[range]SQLUFormatter ..list..    
                     : Reformats the SQL statements over the specified
                       range.  Statement will lined up given the
                       existing indent of the first word.
SQLUCreateColumnList:  Creates a comma separated list of column names
                       for the table name under the cursor, assuming
                       the table definition exists in any open
                       buffer.  The column list is placed in the unnamed
                       buffer.
                       This also uses the g:sqlutil_cmd_terminator.
                       By default a table alias will be added to each of the columns, this is
                       configurable, see documentation (new 1.3.7).
                       This routine can optionally take 2 parameters
                       SQLUCreateColumnList T1
                           Creates a column list for T1
                       SQLUCreateColumnList T1 1
                           Creates a column list for T1 but only for
                           the primary keys for that table.
SQLUGetColumnDef     : Displays the column definition of the column name
                       under the cursor.  It assumes the CREATE TABLE
                       statement is in an open buffer.
SQLUGetColumnDataType
                     : Displays the column datatype of the column name
                       under the cursor.  It assumes the CREATE TABLE
                       statement is in an open buffer.
SQLUCreateProcedure  : Creates a stored procedure to perform standard
                       operations against the table that the cursor
                       is currently under.

    mnemonic explanation
    s - sql
      f   - format
      cl  - column list
      cd  - column definition
      cdt - column datatype
      cp  - create procedure
                                                                            
    To prevent the default mappings from being created, place the
    following in your _vimrc:
        let g:sqlutil_load_default_maps = 0
                                                                            
Customization:
    By default this script assumes a command is terminated by a ;
    If you are using Microsoft SQL Server a command terminator
    would be "go", or perhaps "\ngo".
    To permenantly override the terminator in your _vimrc file you can add
          let g:sqlutil_cmd_terminator = "\ngo"
                                                                            
                                                                            
    When building a column list from a script file (ie CREATE TABLE
    statements), you can customize the script to detect when the
    column list finishes by creating the following in your _vimrc:
          let g:sqlutil_col_list_terminators =
                       \ 'primary,reference,unique,check,foreign'
                                                                            
    This can be necessary in the following example:
          CREATE TABLE customer (
             id         INT DEFAULT AUTOINCREMENT,
             first_name VARCHAR(30) NOT NULL,
             last_name  VARCHAR(60) NOT NULL,
             PRIMARY KEY( id )
          );
