I am trying to join TABLE_1 and TABLE_2, I need to use every one of these fields in my HTML table.I am getting an error about my FROM clause, but I believe there are more errors involved.

I am trying to join TABLE_1 and TABLE_2, I need to use every one of these fields in my HTML table. I am getting an error about my FROM clause, but I believe there are more errors involved.

                           "SELECT "
                            + "TABLE_1.id, "
                            + "TABLE_1.date, "
                            + "TABLE_1.location, "
                            + "TABLE_1.name, "
                            + "TABLE_1.status "
                            + "TABLE_2.date, "
                            + "TABLE_2.location, "
                            + "TABLE_2.name, "
                       开发者_Go百科     + "TABLE_2.type "
                         + "FROM SCHEMA_1.TABLE_1 JOIN SCHEMA_1.TABLE_2 "
                         + "WHERE TABLE_1.id = TABLE_2.id "
                         + "AND add_user = ?");


Change the WHERE TABLE_1.id = TABLE_2.id AND add_user = ? for ON TABLE_1.id = TABLE_2.id WHERE add_user = ?


Try this, instead:

                       "SELECT "
                        + "TABLE_1.id, "
                        + "TABLE_1.date, "
                        + "TABLE_1.location, "
                        + "TABLE_1.name, "
                        + "TABLE_1.status "
                        + "TABLE_2.date, "
                        + "TABLE_2.location, "
                        + "TABLE_2.name, "
                        + "TABLE_2.type "
                     + "FROM "
                     + "  SCHEMA_1.TABLE_1 JOIN SCHEMA_1.TABLE_2 "
                     + "  ON TABLE_1.ID = TABLE_2.ID"
                     + "WHERE add_user = ?");


Join the tables by ON not where
