Teradata" is used in various industries to support decision making, improve business operations, and glean insights from data.
Error 3807 with SQLState" 42S02 typically indicates that the object you are trying to reference in your SQL" statement does not exist in the database". This could be because the object was never created, or because it was deleted at some point.
To troubleshoot this error, you will need to verify that the object you are trying to reference actually exists in the database. You can do this by checking the list of objects in the database and making sure that the object you are trying to access is listed.
If the object does not exist, you will need to create it before you can use it in your SQL" statement. If the object was deleted, you will need to recreate it before you can use it again.
It is also possible that the error is being caused by a typo in the object name, or by using the wrong schema for the object. Make sure that you have spelled the object name correctly and that you are using the correct schema.
If you continue to have trouble, you may want to try accessing the object using a fully qualified name, including the schema name, to make sure that you are accessing the correct object. For example:
SELECT * FROM schema_name.object_name;
The problem may occur during many DDL / DML operations run on a database. The below is the simplest example:
SELECT TOP 10 * FROM XYZ;
There are several reasons for this issue:
- you are trying to run a DML / DDL operation on a table that exists in another database
- you are trying to run a DML / DDL operation on a table that does not exist
- you are trying to run a SELECT / INSERT / UPDATE / DELETE etc. operation on a table that you do not have access to
You are trying to run a DML / DDL operation on a table that exists on a different database
Next, let’s check in which database the table you are looking for is available:
SELECT DataBaseName, TableName, CreateTimeStamp, LastAlterTimeStamp FROM dbc.TablesV WHERE TableName='<your table name>';
If the table you need is available in another database, change the default database using a simple command:
DATABASE <your database name>;
or specify database" in query:
SELECT TOP 10 * FROM <your database name>.XYZ;
You are trying to run a DML / DDL operation on a table that does not exist => SQLState 42s02
Please check if the table you are referring exists in your database. You can check it with the following query:
SELECT DataBaseName, TableName, CreateTimeStamp, LastAlterTimeStamp FROM dbc.TablesV WHERE DataBaseName='<your database name>' AND TableName='<your table name>';
You are trying to run a SELECT / INSERT / UPDATE / DELETE etc. operation on a table that you do not have access to
In Teradata", you can quickly check which objects you have access to. To do this, use two views from the dbc database: AllRightsV and UserRightsV. The AllRightsV view stores permissions for all system users:
SELECT * FROM dbc.AllRightsV WHERE UserName='<your user name>';
Whereas UserRightsV stores all the permissions granted to your user":
SELECT * FROM dbc.UserRightsV WHERE UserName='<your user name>';
I hope this tutorial" helped you to solve your problems!
