The goal of this project is to be able analyze T-Sql statements (similar to sp_depends someprocedurename) to get a list of tables touched with the operation type (UPDATE, INSERT, SELECT or DELETE) without having a connection to the database. If you have connection to the database, then definitely first review if sp_depends satisfies your requirements.

sp_depends does not distinguish between updates and inserts and does not report on data being deleted from tables. And obviously, sp_depends works only on database objects - ie sql stored procedures. If you are running EF framework, that logs SQL statements that you want to analyze, sp_depends will not help. This TSqlParser is also able to find temp tables and table variables used within the SQL text that needs to be analyzed.

Reference TSqlParser.Core.dll and init SqlScriptAnalyzer. The ParserResults object has the collection of tables and stored procedures invoked.

string _sqlText = "INSERT INTO table1
SELECT a, b, c
FROM table2

EXEC pr_some_inner_procedure ";

SqlScriptAnalyzer _analyzer = new SqlScriptAnalyzer();
ParserResults actual = await _analyzer.AnalyzeSqlTextAsync(_sqlText);
Console.WriteLine(actual.ToString());

Parsing Result

• Tables touched
  • table1 - INSERT
  • table2 - SELECT
  • Procedures Invoked
    • pr_some_inner_procedure
