------------------------------
Summary: X LIKE '%%' should simply to X=X
Key: CALCITE-7088
URL: https://issues.apache.org/jira/browse/CALCITE-7088
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.40.0
Reporter: Yu Xu
Assignee: Yu Xu
Fix For: 1.41.0
sql:
{code:java}
"select \"product_name\" like '%' from \"product\""; {code}
would convert as expected:
{code:java}
"SELECT TRUE\nFROM \"foodmart\".\"product\"" ;{code}
but sql：
{code:java}
"select \"product_name\" like '%%' from \"product\"";{code}
would convert not as expected:
{code:java}
"SELECT \"product_name\" LIKE '%%'\nFROM \"foodmart\".\"product\"" ;{code}
LIKE '%%...' should keep the same with LIKE '%'
