我曾经在Postgres管理员中执行的SQL是

SELECT iot1_0."INSERT_ACP_ASSIGN_FUNCTION"(
    character varying '112w',
     1,
    array['1','2','3']
);

如果我执行thsi函数，它正在执行正常但是当我从java代码调用它时抛出异常：

引起：org.postgresql.util.PSQLException：错误：函数 insert_acp_assign_function（字符变化，整数，字符 vary []）不存在提示：没有函数匹配给定的名称和参数类型。您可能需要添加显式类型转换位置：15点 org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse（QueryExecutorImpl.java:2270）在 org.postgresql.core.v3.QueryExecutorImpl.processResults（QueryExecutorImpl.java:1998）在 org.postgresql.core.v3.QueryExecutorImpl.execute（QueryExecutorImpl.java:255）在 org.postgresql.jdbc2.AbstractJdbc2Statement.execute（AbstractJdbc2Statement.java:570）在 org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags（AbstractJdbc2Statement.java:420）在 org.postgresql.jdbc2.AbstractJdbc2Statement.execute（AbstractJdbc2Statement.java:413）在 org.apache.commons.dbcp.DelegatingPreparedStatement.execute（DelegatingPreparedStatement.java:169）

请帮助我对postgres非常新。我好多天都在挣扎。

Answer 1

您是否尝试过添加“iot1_0”。打电话？您是否在PgAdmin中从同一用户运行它？您可能还想从Java代码中运行queries listing available procedures之一 - 以查看哪些方法应该可见。

没有函数匹配给定的名称和参数类型。您可能需要添加显式类型转换。职位：15 :: Callable Statement Spring
