The only special thing about the contextmenu is that you can prepare any SQL statements. Just put them in the file cfg/sqlStatements.sqlFree and they will appear in the contextmenu.

• Send statement to the database. Only one statement is allowed in the input window. sqlFree will automatically change to the resultviewer.
• Check statement for placeholders. If you have been using placeholders like "$x" or "##choose x##" in your statement instead of real values then you will get a mappingtable. There you can enter the real values which shall be used when sending the SQL statement.
• Visualize statement in the querybuilder. Please make sure that you have chosen the schema you are working on in the "visual SQL Query builder"-node. 
  sqlFree will automatically change to the SQL builder view.
