FEATURE 1 - SQL VALIDATOR
__________________________________
This application provides a validator that intends to check if a DML or DDL statement is syntactically correct. This feature is fantastic for those who are starting to learn the SQL language.
Functionalities:
1.1) Capture SQL code directly from the PC monitor (and directly from SQL Server, Oracle, MySQL or Access query window)
1.2) Write an SQL statement directly in the application
2) Step-by-step validation with clear error indication (with suggestions and automatic corrections)

Note:
Select and Create statement is not yet available for Validation. Likewise, sub-queries, expressions and column and table names using spaces are not yet evaluated.
We are working on this feature which will be available in a future release.
Statements available:
- INSERT
- UPDATE
- DELETE
- ALTER (Database, Table or Indexes)
- DROP (Database, Table or Constraints)
