java - How do I execute PreparedStatement(select object_id()) in sybase iq? -


we have small jdbc application talks sybase iq database does:

string objectname = "sys.syswebservice";  //the actual value of objectname not matter. //it view object in sys schema  preparedstatement preparedstatement =     connection.preparestatement("select object_id(?)"); preparedstatement.setstring(1, objectname); preparedstatement.executequery();

we getting error:

java.sql.sqlexception: jz0sa: prepared statement: input parameter not set, index: 0.s

i looked @ http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc39001.0700/html/prjdbc0700/chdgjjig.htm

jz0sa: prepared statement: input parameter not set, index: _____. action: sure each input parameter has value.

when change code

setstring(0, objectname)

i getting:

java.lang.arrayindexoutofboundsexception: -1     @ com.sybase.jdbc4.jdbc.sybpreparedstatement.a(unknown source)     @ com.sybase.jdbc4.jdbc.sybpreparedstatement.a(unknown source)     @ com.sybase.jdbc4.jdbc.sybpreparedstatement.a(unknown source)     @ com.sybase.jdbc4.jdbc.sybpreparedstatement.setstring(unknown source)

we using jconn-4.0.jar:

manifest-version: 1.0 created-by: 1.6.0_03 (sun microsystems inc.) main-class: sybversion  name: com/sybase/jdbcx/ implementation-vendor: "sybase, inc." specification-title: "jconnect jdbc 4.0" implementation-title: "com.sybase.jdbcx" implementation-version: "build (26502)" specification-version: "7.0" specification-vendor: "sybase, inc."

can tell me doing wrong? thank you.

despite api doc might say, think parameter index must zero-based, maybe bug in jdbc driver using. try zero-based index. setstring(0,....);
