st_geometry_astext_format option

Controls how spatial values are converted from a geometry to text.

Allowed values

The list of values supported for this option is identical to the list of parameters (including sub-parameters) documented for the ST_AsText method.

This option is used to determine how a geometry is converted to text. The following are the two main contexts in which the option is used:

  • fetching a value as text from a client application

  • Executing a CAST statement. For example: CAST( geometry-expression AS LONG VARCHAR )

Assignments from geometry types to CHAR types give an error in contexts other than fetching from a client application and the CAST statement. For example, you cannot call a function or procedure that takes a CHAR parameter and pass a geometry, nor can you assign a geometry to a LONG VARCHAR variable.
