ErrorReasonResolution

Failure: DQL statements are not allowed.

The ELT Execute Snap does not support Data Query Language (DQL) and hence statements containing SELECT and WITH are not allowed.

Remove any DQL statements (containing SELECT, WITH) and enter one of the following statement types:

  • Data Definition Language (DDL): CREATE, ALTER, DROP, TRUNCATE, RENAME and so on. 

  • Data Control Language (DCL): GRANT, REVOKE

  • Data Manipulation Language (DML): INSERT, UPDATE, DELETE, MERGECALL and so on.

No matching signature for operator = for argument types: INT64.

(Target CDW: BigQuery)

BigQuery treats the values of Pipeline parameters as String, by default. Passing a value with any other data type causes this error (INT64 in this example).

Cast any non-String Pipeline parameter used in your SQL statement to its target data type for the Snap to work as expected.

Ex: Consider using SELECT * FROM pipe.param01 WHERE id = cast( _id as INT ); instead of SELECT * FROM pipe.param01 WHERE id = _id;

Keyword RANGE is not acceptable as a column name.

(CDW: Databricks Lakehouse Platform)

This can happen with any reserved keyword if it is used as a column/field name in the table to be created.Ensure the enclose such column names (reserved keywords) between backticks (`). For example: `RANGE' STRING.

[Simba][SparkJDBCDriver](500051) ERROR processing query/statement. Error Code: 0

Cannot create table ('<schema name>`.`<table name>`'). The associated location (`…<table name>`) is not empty but it's not a Delta table

(CDW: Databricks Lakehouse Platform)

A non-Delta table that currently exists is corrupted and needs to be dropped from the schema before creating a Delta-formatted table.

However, this corrupted table can only be dropped manually—by accessing the DBFS through a terminal. The Pipeline cannot perform this operation.

Drop the corrupted table and then try creating the new table in Delta format (using the Pipeline).

To drop the corrupted table, from the terminal, access the DBFS and run the following command:

dbfs rm -r dbfs:/<table_path>

Syntax error when database/schema/table name contains a hyphen (-) such as in default.schema-1.order-details.

(CDW: Azure Synapse)

Azure Synapse expects any object name containing hyphens to be enclosed between double quotes as in "<object-name>".Ensure that you use double quotes for every object name that contains a hyphen when your target database is Azure Synapse. For example: default."schema-1"."order-details".
