Question

StringBuilder sqlQry = new StringBuilder();
sqlQry.append("SELECT LIB, PATH")
.append(" FROM OBJ")
.append(" INNER JOIN SRC ON SRC.MBR = OBJ.LOBJ")
.append(" WHERE  TYPE = '*PGM'")
.append(" AND SRC.PATH LIKE '").append("?").append("%'");

PreparedStatement ps = accssConn.prepareStatement(sqlQry.toString());
ps.setString(1, path);

rs = ps.executeQuery();

大家好，我得到了以下异常

[jcc][10145][10844][3.63.123] Invalid parameter 1: Parameter index is out of range. ERRORCODE=-4461, SQLSTATE=42815

列限制为255，路径为=“C：\ Documents and Settings \ xyz \ Desktop \ xyzs”，并且使用statement.So运行正常，它在预准备语句中抛出异常的原因是什么。

Answer 1

StringBuilder sqlQry = new StringBuilder();

sqlQry.append("SELECT LIB, PATH")
.append(" FROM OBJ")
.append(" INNER JOIN SRC ON SRC.MBR = OBJ.LOBJ")
.append(" WHERE  TYPE = '*PGM'")
.append(" AND SRC.PATH LIKE ").append("?");

PreparedStatement ps = accssConn.prepareStatement(sqlQry.toString());

ps.setString(1, path + "%");

检查你的单引号我认为其中一个缺少收盘报价。还可以尝试将单引号更改为双引号并将其转义为“* PGM”

在为select查询使用预准备语句时获取SQL异常
