## What is Learn & Validate SQL?

Will you start learning SQL in Oracle?
Did you forget the statements many times?
Do you no longer remember the syntax and the result of an statement?

Developed to easily learn SQL Programming (T-SQL) for Oracle

. . . . . . . . . . . . . . . . . . . . . 

This App acts as a reference for the PL-SQL language

Validate SQL code through Augmented Reality (Text Recognition - possibility to take a picture of the code on your PC)

. . . . . . . . . . . . . . . . . . . . . 

Learn DML & DDL statements with description, syntax, notes and examples 

For each statement is presented:

Detailed description of the statement/command purpose

Syntax of the statement with the various options

Two examples executed from a real table (Automobile Table)


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)
