Description

This App acts as a reference for the SQL language, with two main features: 1) Validate SQL code through Augmented Reality (Text Recognition) (possibility to take a picture of the code on your PC) 2) Learn DML & DDL statements with description, syntax, notes and examples For each statement is presented: a) Detailed description of the statement/command purpose b) Syntax of the statement with the various options c) Two examples executed from a table (Automobile Table) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

This application provides a validator that intends to check if a DML or DDL instruction 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 (with or without columns name) - UPDATE (with multiples SET and with or without WHERE condition) - DELETE (with or without WHERE condition) - ALTER (Database, Table or Indexes) - DROP (Database, Table or Constraints) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
