Spring Batch Throwing an error 'Object 'BATCH_JOB_SEQ' is not a sequence object' - sql

Question

I am working on a spring batch project, I have used sql server as a local database, used this link to create the db script for batches but now get below given error.
23463 [main] WARN  o.s.b.c.c.a.DefaultBatchConfigurer - No transaction manager was provided, using a DataSourceTransactionManager

com.microsoft.sqlserver.jdbc.SQLServerException: Object 'BATCH_JOB_SEQ' is not a sequence object.
When I call the SQL query
SELECT name, type_desc FROM sys.objects WHERE name=N'BATCH_JOB_SEQ';
The returned result is
Name: type_desc:
BATCH_JOB_SEQ SEQUENCE_OBJECT

In Spring Batch 4, tables were used to emulate sequences for SQL Server and a SqlServerMaxValueIncrementer was used to increment IDs.
In Spring Batch v5, we changed SQL Server support to use sequences instead of emulating them with tables. Version 5 uses a SqlServerSequenceMaxValueIncrementer to increment IDs.
The link you shared points to the DDL script of the main branch, which is for Spring Batch v5. So in your case, you either need to use the DDL script for v4 (which you can find here), or upgrade your application to Spring Batch 5 (the last version is 5.0.0-RC2, the GA is planned later this November 2022).
