You can use SQL in Teiid to issue queries and define view transformations. For more information about how SQL is used in virtual procedures and update procedures, see Procedure language. Nearly all these features follow standard SQL syntax and functionality, so you can use any SQL reference for more information.

There are 4 basic commands for manipulating data in SQL, corresponding to the create, read, update, and delete (CRUD) operations: INSERT, SELECT, UPDATE, and DELETE. A MERGE statement acts as a combination of INSERT and UPDATE.

You can also execute procedures by using the EXECUTE command, procedural relational command. For more information, see Procedural relational command, or Anonymous procedure block.
