如何使用JOOQ从模板和参数占位符生成sql？

Question

I get the sql template like this with jOOQ 3.11.11.

DSLContext context = new DefaultDSLContext(conf);
Query query = context.select().from("table1").where(DSL.field("report_date").eq(DSL.param("bizdate")));
String sqlTemp = context.renderNamedParams(query);

I store the plain sql template.

select * from table1 where report_date = :bizdate

The param 'bizdate' is decided by realtime query.
So. How to generate the real sql

select * from table1 where report_date = '20190801'

with the stored sql template string and the realtime input date '20190801'.

Answer 1

You can use this:

context.resultQuery(sqlTemp, DSL.param("bizdate", "20190801")).fetch();

See DSLContext.resultQuery(String, QueryPart...)
