java - How do I insert last_insert_id using preparedStatement? -


i facing difficulty in inserting " last_insert_id" in prepared statement.i got how select last_insert_id in prepared statement below:

preparedstatement getlastinsertid = con.preparestatement("select last_insert_id()");

when use same procedure inserting last_insert_id in preparedstatement this:

1.  preparedstatement pst =  con.preparestatement("insert introducer_table  values(?,?,?,?)"); 2.      3.     //introducer details database 4.       pst.setstring(1,last_insert_id()); 5.     pst.setstring(2, nameofintroducer); 6.     pst.setstring(3, accountno); 7.     pst.setstring(4, signofintroducer);

im getting 'null' value in first column.can 1 me come out problem

if doing both save actions @ time use getgeneratedkeys(), it's pretty java.

i'm not sql guru, here found way generated id using getgeneratedkeys()

    long generatedid= 0l;     statement = con             .getconnection()             .preparestatement(                     "insert  new_user set name= ? , contact= ? , ....",                     statement.return_generated_keys);     statement.setstring(1, "examplename");     statement.setstring(2, "examplecontact");     ------     statement.executeupdate();     resultset generatedkeys = statement.getgeneratedkeys();     if (generatedkeys.next()) {         generatedid = generatedkeys.getlong(1);// here generated id , use  insert in introducer_table     }       preparedstatement pst =  con.preparestatement("insert introducer_table  values(?,?,?,?)");           //introducer details database          pst.setstring(1, generatedid);          pst.setstring(2, nameofintroducer);          pst.setstring(3, accountno);          pst.setstring(4, signofintroducer);

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

[dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
