Use

In the SQL Editor, you can enter, execute, and save SQL statements.

More information: Entering and Executing SQL Statements

The following rules apply:

  • You can write SQL syntax elements in either upper or lower case.

  • You can add any number of spaces and line breaks.

  • To force the system to take the case into account for database object identifiers (such as table names) and values in the form of literals, enter the identifier between single quotation marks: '<identifier>'.

  • To comment out a row, use // or -- at the start of the row.

  • To separate several SQL statements from one another, enter a commented-out separator line.

If you press the key combination CTRL+ Space after a word in the SQL editor, a list is displayed containing default values for this word. You must have already defined a corresponding template for this word. More information: Configuring Database Studio, Templates section.
