SQL Formatter

SQL Formatter improves the readability of SQL statements. It formats SQL statements by adding/deleting rows and indenting context, and is used to format migrated output files. It can also be used for importing files.

Use the formattedSourceRequired parameter to enable/disable the SQL formatter for the source SQL files. If this parameter is set to true, the copy of the input file is formatted and saved to the Output path\formattedSource directory.

SQL Formatter also supports Teradata SQL migration and Oracle SQL migration. SQL scripts in Teradata Perl file migration are also formatted. The Oracle (Beta) tool does not support SQL Formatter.
