无法了解数十亿行的更新计数INSERT

Question

I am running a Netezza SQL query that is creating a table from a select statement returning almost 8 billion rows. Here is the query:

CREATE TABLE
    table1 AS
    (
        SELECT
            column1
        FROM
            table2 qt
        WHERE
           qt.column1 = '2016-04-04'
        UNION ALL
        SELECT
            column1
        FROM
            table3 qt
        WHERE
           qt.column1 = '2016-04-04'
   )

The driver is throwing this error:

org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation; uncategorized SQLException for SQL []; SQL state [UNDEFINED]; error code [0];   
    --- The error occurred while applying a parameter map.  
    --- Check the statement (update failed).  
    --- Cause: Unable to fathom update count INSERT 0 7779737732

Does anyone know what's causing this?

Answer 1

I think you are running into a JDBC driver limitation. If you run a INSERT, UPDATE, CREATE AS SELECT via JDBC and the number of rows INSERTed, UPDATEd or CREATEd exceeds 2147483647, you will receive an error message similar to the following:

Unable to fathom update count INSERT 0 5120000160

The above error message may be different given whether an INSERT, UPDATE or CREATE as SELECT and given the number of rows actually affected. This is a limitation of JDBC specification itself.
