# Proposed changes
This pr mainly to supplement the syntax of the previous pr(#8861), it
supports users to manually inject statistics, including table, partition, and
column statistics.
Modify table or partition statistics:
`
ALTER TABLE table_name
SET STATS ('k1' = 'v1', ...) [ PARTITIONS(p_name1, p_name2...) ]
`
Modify column statistics:
`
ALTER TABLE table_name MODIFY COLUMN columnName
SET STATS ('k1' = 'v1', ...) [ PARTITIONS(p_name1, p_name2...) ]
`
Some notes:
- Only support statistics injected into olap type tables.
- Statistics injected into temporary partitions are not supported.
- When injecting statistics, if it is a partitioned table, users need to
specify a partition name.
- If multiple partitions are specified, the same stats will be injected on
multiple partitions.
- The current code also has mock statistics @zhengshij
