在 Eclipse 中，我收到此错误:**错误 ORA-01000:超出最大打开游标数 我终于在 block 中关闭了连接，但我不知道为什么会收到此错误，这是我的代码 JAVA。 请帮助我!
for (DossierAMO dos = null; it.hasNext();) {
PreparedStatement ps = null;
ResultSet rs = null;
PreparedStatement ps2 = null;
ResultSet rs2 = null;
try {
dos = (DossierAMO) it.next();
//PreparedStatement ps = null;
//ResultSet rs = null;
/*try
*
{*/
System.out.println("Imma"+dos.getImma());
ps = cnnOracle.getConnexion().prepareStatement(
"select count(IMM_IMM_V_NUM_IMM) from d_salaire@prod_dist where SAL_C_DS =21 and IMM_IMM_V_NUM_IMM =?",
ResultSet.TYPE_FORWARD_ONLY,
ResultSet.CONCUR_READ_ONLY
);
ps.setString(1,dos.getImma());
rs = ps.executeQuery();
if (rs.next()){
if (rs.getInt(1) != 0)
//System.out.println("> Ecriture des dossiers d'indus dans le fichier d'indus2");
fichierIndius2.ecrireDossier(dos);
else

return;
}
finally{
if (rs != null)
try {
rs.close();
} catch (Exception exx) {
}
if (rs2 != null)
try {
rs2.close();
} catch (Exception exx) {
}
if (ps != null)
try {
ps.close();
} catch (Exception exx) {
}
if (ps2 != null)
try {

}
最佳答案
" i don't know why i'm getting this error"
会不会是这个错字？
if (ps2 != null)
try {
ps.close();
} catch (Exception exx) {
}
您正在关闭 ps 而不是 ps2
