T-SQL checker

This program, for a given Transact-SQL file, outputs tokens and elements of T-SQL grammar produced by ANTLR (ANother Tool for Language Recognition).

Binaries

Windows and Linux binaries can be downloaded from releases.

Usage

Input select.sql:

select * -- inline comment
From   TableName /* multiline
                      comment */
WHERE  someField > ALL (SELECT [val] FROM [AnotherTable]);

Execution:

./tsql-checker.exe select.sql

Output select.tokens:

select
*
From
TableName
WHERE
someField
>
ALL
(
SELECT
[val]
FROM
[AnotherTable]
)
;
<EOF>

Notes

• TSqlLexer.h, TSqlLexer.cpp, TSqlParser.h and TSqlParser.cpp are generated by ANTLR. They can be updated to the newest version of ANTLR4 grammar for T-SQL by running PowerShell script update-parser-lexer.ps1.
• The program does not support non-Unicode input files.
