我在 kafka 中有一个 JDBCSourceConnector,它使用查询从数据库流式传输数据。 但是我为选择数据而编写的查询有问题。
我在 Postgres psql 和 DBeaver 中测试了查询。它工作正常,但在 kafka 配置中,它会产生 SQL 语法错误
错误
ERROR Failed to run query for table TimestampIncrementingTableQuerier{name='null', query='select "Users".* from "Users" join "SchoolUserPivots" on "Users".id = "SchoolUserPivots".user_id where school_id = 1 and role_id = 2', topicPrefix='teacher', timestampColumn='"Users".updatedAt', incrementingColumn='id'}: {} (io.confluent.connect.jdbc.source.JdbcSourceTask:221) org.postgresql.util.PSQLException: ERROR: syntax error at or near "WHERE"
