Description

This error signifies that a variable within an SAP SQLScript procedure or function is being used in a context that expects a table type, but the variable itself has not been declared as such. It commonly occurs during the compilation or execution of SQLScript code due to a fundamental mismatch in how a variable is defined versus how it's being utilized.

Error Message

ERR_SQLSCRIPT_VARIABLE_NOT_TABLE_TYPE

🔍

Known Causes

3 known causes

⚠️

Incorrect Variable Declaration

A variable intended to hold a result set or table structure was declared as a scalar type (e.g., INT, VARCHAR) instead of a table type.

⚠️

Misuse of Scalar Variable

A scalar variable is being referenced in a SQL operation that specifically requires a table variable, such as in a `FROM :variable` clause.

⚠️

Undefined Table Type

The table type referenced by a variable declaration is either non-existent or inaccessible within the current SQLScript scope.

Solutions

3 solutions available

1. Correct Variable Declaration in SQLScript easy

Ensure that variables intended to hold table data are declared as table types.

1

Identify the SQLScript procedure or function where the error occurs. This can be done by examining the application logs or tracing the execution that leads to error 2880.

2

Locate the variable declaration that is causing the type mismatch. The error message 'ERR_SQLSCRIPT_VARIABLE_NOT_TABLE_TYPE' directly points to a variable that is expected to be a table type but is not.

3

Modify the variable declaration to explicitly define it as a table type. If the variable is meant to hold data from a specific SAP table, use the corresponding table type. If it's for a custom structure, define a custom table type.

DECLARE my_table_variable MY_CUSTOM_TABLE_TYPE;
-- or if using an existing SAP table type:
DECLARE my_sap_table_variable MY_SAP_TABLE_TYPE;
-- Incorrect declaration would look like:
-- DECLARE my_variable VARCHAR(100); -- if intended for table data

4

If the variable is intended to be populated with the result of a SELECT statement, ensure the SELECT statement's output structure matches the declared table type. If not, adjust the SELECT or the table type definition.

SELECT column1, column2 FROM my_source_table;
-- Ensure MY_CUSTOM_TABLE_TYPE has columns column1 and column2 with compatible data types.

2. Align SELECT Statement with Table Type medium

Match the columns and data types of a SELECT statement to the target table type variable.

1

Pinpoint the SQLScript code that assigns data to the problematic variable. This usually involves a `SELECT INTO` statement or an assignment within a cursor loop.

2

Examine the `SELECT` statement's projection list (the columns being selected) and their data types.

SELECT col_a, col_b, col_c FROM some_table WHERE ...

3

Review the definition of the table type variable to which the `SELECT` statement's results are being assigned.

DECLARE target_table_var MY_TARGET_TABLE_TYPE;
-- And inspect the definition of MY_TARGET_TABLE_TYPE

4

Ensure that the number, order, and data types of the columns in the `SELECT` statement precisely match the fields defined in the `MY_TARGET_TABLE_TYPE`. Minor discrepancies in data type compatibility (e.g., a longer string type than required) can also cause this error. Adjust the `SELECT` statement or the table type definition as needed.

DECLARE my_var MY_TABLE_TYPE;
my_var = SELECT col1, col2 FROM source_table;
-- If MY_TABLE_TYPE has fields 'FIELD1' and 'FIELD2' but the SELECT returns 'col1' and 'col2', you need to alias them:
my_var = SELECT col1 AS FIELD1, col2 AS FIELD2 FROM source_table;

3. Review Stored Procedure/Function Parameters medium

Verify that input and output parameters of SQLScript routines are correctly typed as table types when necessary.

1

Identify the stored procedure or function that is throwing error 2880. This might be a custom enhancement or a standard SAP routine.

2

Examine the procedure or function signature, paying close attention to any parameters that are intended to accept or return table data.

CREATE PROCEDURE MY_PROCEDURE (IN in_table_param MY_TABLE_TYPE, OUT out_table_param MY_TABLE_TYPE, IN scalar_param INT)
-- ...

3

Confirm that these parameters are declared with the appropriate table type. If a parameter is intended to receive a table, it should be declared as `IN table_type_name`. If it's meant to return a table, it should be declared as `OUT table_type_name`.

CREATE PROCEDURE MY_PROCEDURE (IN in_data TABLE(col1 INT, col2 VARCHAR(100))) -- Incorrect for table type
-- Should be:
CREATE PROCEDURE MY_PROCEDURE (IN in_data MY_CUSTOM_TABLE_TYPE)

4

When calling this procedure or function from another SQLScript routine or application, ensure that the arguments passed for table-type parameters are indeed table-like structures (e.g., a table variable or a result set that can be implicitly converted).

DECLARE temp_data MY_CUSTOM_TABLE_TYPE;
-- Populate temp_data...
CALL MY_PROCEDURE(IN temp_data, OUT result_table);
