当我尝试将一个 Java 数组 int 传递给 Oracle PLSQL 时，我得到了一个异常。我使用文档中的示例，但对我来说它不起作用。
我将 JDK 1.8 和 ojdbc8 用于 Oracle 18 XE 数据库。
@Test
void flush() {
try {
final Driver oraDriver = new OracleDriver();
System.out.println("Driver Major version is "+oraDriver.getMajorVersion());
final Properties myProperties = new Properties();
myProperties.setProperty("user", "kafka");
myProperties.setProperty("password", "kafka");
Connection conn = oraDriver.connect(JDBC_URL, myProperties);
OracleCallableStatement procin = (OracleCallableStatement)
conn.prepareCall("declare type t_indices is table of pls_integer index by pls_integer;\n" +
"a_indices t_indices;\n" +
"begin\n" +
" a_indices := ?;\n" +
"end;"
);
// Associative Array bind value
int[] values = {1, 2, 3};
// maximum length of the Associative Array bind value. This
// value defines the maximum possible "currentLen" for batch
// updates. For standalone binds, "maxLen" should be the
// same as "currentLen".
int maxLen = values.length;
// actual size of the Associative Array bind value
int currentLen = values.length;
// Associative Array element type
int elemSqlType = OracleTypes.NUMBER;
// Associative Array element length in case the element type
// is CHAR, VARCHAR or RAW. This value is ignored for other
// types.
int elemMaxLen = 0;
// set the value
procin.setPlsqlIndexTable(1, values,
maxLen, currentLen,
elemSqlType, elemMaxLen);
// execute the call
procin.execute();
}
catch (Exception e) {
throw new ConnectException(e);
}
}
这基于“访问 PL/SQL 关联数组”一章中的示例。https://docs.oracle.com/database/121/JJDBC/oraint.htm#JJDBC28179。
输出/错误文本如下。我预计没有错误。解决办法是什么？
