Description
The short_column_names pragma, in conjunction with
the full_column_names pragma,
controls how the database connection specifies and formats
column names in result sets. If short_column_name is enabled, output column
expressions that consist of a single named table column will be
clipped to only include the column name. This pragma is on by
default.
The general rules for output names are:
If
short_column_namesis enabled and the output column is an unmodified source column, the result set column name iscolumn_nameIf
full_column_namesis enabled and the output column is an unmodified source column, the result set column name istable_name.column_nameThe result set column name is the text of the column expression, as given.
If full_column_names and short_column_names are both enabled, short_column_names will override
full_column_names.
Note that there is no guarantee the
result set column names will remain consistent with future
versions of SQLite. If your application depends on specific,
recognizable column names, you should use an AS clause.
