The data type of an argument that you pass to a geospatial system function does not need to exactly match the corresponding declared argument type as described in the function description. If the argument type is a compatible type, as listed in the following table, Teradata Database tries to implicitly cast the argument.

Declared Argument Type Compatible Argument Types
DECIMAL BYTEINT, SMALLINT, INTEGER, or BIGINT
FLOAT BYTEINT, SMALLINT, INTEGER, BIGINT, DECIMAL, or NUMERIC
INTEGER BYTEINT or SMALLINT
VARCHAR CHAR

To pass an argument where the data type is not an exact match and is not a compatible type according to the preceding table, you must explicitly convert the argument.
