以下、テーブルを作成しています。
public static final String CREATE_SQL = "CREATE TABLE " +DATABASE_TABLE +
"(ID number(10,0), " +
" CGUID VARCHAR(255), " +
" PGUID VARCHAR(255), " +
" SGUID VARCHAR(255), " +
" USERID VARCHAR(255), " +
" ULOC VARCHAR(255), " +
" SLOC VARCHAR(255), " +
" PLOC VARCHAR(255), " +
" ALOC VARCHAR(255), " +
" SITEID VARCHAR(255), " +
" ATTRIBUTEID VARCHAR(255), " +
" ATTRIBUTEVALUE VARCHAR(255), " +
" PRIMARY KEY ( ID ))";
これは、データベース テーブルを更新しようとしているときの以下の UPSERT_SQL クエリです 。SQL を確認しましたが、式が欠落している場所を見つけることができません。以下のSQLは間違っていますか？
public static final String UPSERT_SQL = "MERGE INTO " +DATABASE_TABLE+ " USING ( SELECT ? AS ID, " + // We will maybe add this record
" ? AS CGUID, " +
" ? AS PGUID, " +
" ? AS SGUID, "+
" ? AS USERID, "+
" ? AS ULOC, "+
" ? AS SLOC, "+
" ? AS PLOC, "+
" ? AS ALOC, "+
" ? AS SITEID, "+
" ? AS ATTRIBUTEID, "+
" ? AS ATTRIBUTEVALUE, "+
" FROM dual ) maybe "+
" ON (maybe.ID = "+DATABASE_TABLE+".ID) "+
" WHEN MATCHED THEN "+
// We only need update the fields that might have changed
" UPDATE SET " +DATABASE_TABLE+ ".ULOC = maybe.ULOC, " +DATABASE_TABLE+ ".SLOC = maybe.SLOC, " +DATABASE_TABLE+ ".PLOC = maybe.PLOC, " +DATABASE_TABLE+ ".ALOC = maybe.ALOC "+
" WHEN NOT MATCHED THEN "+
// Insert new record
" INSERT VALUES (maybe.ID, maybe.CGUID, maybe.PGUID, maybe.SGUID, maybe.USERID, maybe.ULOC, maybe.SLOC, maybe.PLOC, maybe.ALOC, maybe.SITEID, maybe.ATTRIBUTEID, maybe.ATTRIBUTEVALUE)";
そして下から、その UPSERT_SQL ステートメントを実行しています。
LnPDataConstants.PSTMT = LnPDataConstants.DB_CONNECTION.prepareStatement(LnPDataConstants.UPSERT_SQL); // create a statement
LnPDataConstants.PSTMT.setInt(1, (int) ind);
LnPDataConstants.PSTMT.setString(2, LnPDataConstants.CGUID_VALUE);
LnPDataConstants.PSTMT.setString(3, LnPDataConstants.PGUID_VALUE);
LnPDataConstants.PSTMT.setString(4, LnPDataConstants.SGUID_VALUE);
LnPDataConstants.PSTMT.setString(5, LnPDataConstants.UID_VALUE);
LnPDataConstants.PSTMT.setString(6, LnPDataConstants.ULOC_VALUE);
LnPDataConstants.PSTMT.setString(7, LnPDataConstants.SLOC_VALUE);
LnPDataConstants.PSTMT.setString(8, LnPDataConstants.PLOC_VALUE);
LnPDataConstants.PSTMT.setString(9, LnPDataConstants.ALOC_VALUE);
LnPDataConstants.PSTMT.setString(10, LnPDataConstants.SITEID_VALUE);
LnPDataConstants.PSTMT.setString(11, "10200");
LnPDataConstants.PSTMT.setString(12, attrValue1.toString().split("=")[1]);
LnPDataConstants.PSTMT.executeUpdate();
