Variable Objects

Note

The DB API definition does not define this object.

Variable.actualElements

This read-only attribute returns the actual number of elements in the variable. This corresponds to the number of elements in a PL/SQL index-by table for variables that are created using the method Cursor.arrayvar(). For output variables in a DML returning statement this value corresponds to the number of rows returned. For all other variables this value will be identical to the attribute numElements.

Variable.bufferSize

This read-only attribute returns the size of the buffer allocated for each element in bytes.

Variable.getvalue([pos=0])

Return the value at the given position in the variable.

Variable.inconverter

This read-write attribute specifies the method used to convert data from Python to the Oracle database. The method signature is converter(value) and the expected return value is the value to bind to the database. If this attribute is None, the value is bound directly without any conversion.

Variable.numElements

This read-only attribute returns the number of elements allocated in an array, or the number of scalar items that can be fetched into the variable or bound to the variable.

Variable.outconverter

This read-write attribute specifies the method used to convert data from from the Oracle to Python. The method signature is converter(value) and the expected return value is the value to return to Python. If this attribute is None, the value is returned directly without any conversion.

Variable.setvalue(pos, value)

Set the value at the given position in the variable.

Variable.size

This read-only attribute returns the size of the variable. For strings this value is the size in characters. For all others, this is same value as the attribute bufferSize.

Variable.type

This read-only attribute returns the type of the variable for those variables that bind Oracle objects (it is not present for any other type of variable).

Variable.values

This read-only attribute returns a copy of the value of all actual positions in the variable as a list. The number of items in the list will correspond to the value of the actualElements attribute.
