PostgreSQL stepping on the pit | error: operator does not exist: UUID = character varying

Business scenario ：

stay MyBatis Chinese vs Postgresql Database table data update operation , Report the following error ：

• Caused by: org.postgresql.util.PSQLException: ERROR: column “data” is of type jsonb but expression is of type character varying
  Suggest ：You will need to rewrite or cast the expression.
  

• Caused by: org.postgresql.util.PSQLException: ERROR: operator does not exist: uuid = character varying
  Suggest ：No operator matches the given name and argument types. You might need to add explicit type casts.

reason ：

because Postgresql The data type of the database is the same as MySQL atypism , Lead to habitual thinking in MyBatis Write in database sql sentence , Result in an error . The reason is actually the same , Is the data type of the accepted parameter and Postgresql Inconsistency of database .

I am here. uuid and data Namely uuid The type and jsonb type , Here's the picture ：

then MyBatis Medium sql as follows ：

This is the scene .

resolvent ：

Add the corresponding type conversion after each type , Such as uuid The type and jsonb, Add :: type Such a format is sufficient , as follows ：

thus , Problem solving ！
