Just try with
Delete From "TableName" Where "Some Condition" : if you want to delete data based on some conditions.
else
Delete From "TableName"

Hi,

You have not supplied a WHERE clause in your SQL and it looks like you have mixed up the syntax between an INSERT statement and the DELETE Statement.

With Insert Statements, you are creating new records so you pass in the table columns and the values.

With DELETE, SELECT and UPDATE statements you either apply to the whole table or you add a WHERE clause to apply to a subset of the data. i.e. If I run DELETE FROM MyUserTable - I have deleted every record from MyUserTable if I run DELETE FROM MyUserTable WHERE (UserID = 5) then I have only deleted the records where the UserID column has a value of 5.

If you carry out a SQL Delete command , you are deleting the record so you do not specify the columns.

If however, you want to "delete" the values in certain record(s) for specific columns then you would apply a SQL Update command i.e. UPDATE MyUserTable SET Title='' WHERE (UserID =5) would "blank" the title column of any record where the UserID column equals 5.
