(CVTYPE('colvarname',flag))
Returns the data type for a given column or variable name.
To return the data type for a given column, a zero "0" flag must be used. To return the data type for a given variable, the one "1" flag must be used.
Example 01.
SET VAR vCustIDType TEXT = (CVTYPE('CustID',0))
SET VAR vEmpCity TEXT = (CVTYPE('EmpCity',0))
SHOW VARIABLES
Variable = Value Type
------------------ --------------- -------
vCustIDType = INTEGER TEXT
vEmpCity = TEXT,20 TEXT
Example 02.
SET VAR vCustIDType TEXT = (CVTYPE('CustID',0))
SET VAR vVarInquiry TEXT = (CVTYPE('vCustIDType',1))
SHOW VARIABLES
Variable = Value Type
------------------ --------------- ------
vEmpCity = TEXT,20 TEXT
vVarInquiry = TEXT,7 TEXT
Notes:
•When using the zero flag to return column data types, you must be connected to a database.
•When returning a TEXT data type, the length is included and is separated with a comma. When returning a NUMERIC data type, the precision and scale are separated with commas.
