Description

Defect Description:

When insert UCS2 charset with 32K or 200K column length, an error "java.sql.SQLException: *** ERROR[8402] A string overflow occurred during the evaluation of a character expression. Conversion of Source Type:NCHAR VARYING(REC_NCHAR_V_UNICODE,96000 BYTES,UTF8) Source Value" will be happened.

Test Environment:

codes' version: commit 1c7265ab7addcd088151904b9139337a29a52d90

Test Steps:

Step 1. create a table.

405 sql = "create table tblcolumnsize32kWithUCS2(c1 char(16000) character set UCS2 collate default null, c2 char(16000) character set UCS2 collate default null)";

Step 2. insert UCS2 sql text.

409 String a = "";
410 String b = "";
411
412 for (int i = 1; i < 16000; i++)

{ 413 //a += URLEncoder.encode("a", "UTF-16BE"); 414 //b += URLEncoder.encode("b", "UTF-16BE"); 415 a += new String("a".getBytes(), "UTF-16BE"); 416 b += new String("b".getBytes(), "UTF-16BE"); 417 }

418
419 //a += URLEncoder.encode("E", "UTF-16BE");
420 //b += URLEncoder.encode("E", "UTF-16BE");
421 a += new String("E".getBytes(), "UTF-16BE");
422 b += new String("E".getBytes(), "UTF-16BE");
423
424 sql = "insert into tblcolumnsize32kWithUCS2(c1, c2) values('" + a + "', '" + b +"')";
425 iRet = stmt.executeUpdate(sql);
426 assertEquals(1, iRet);

in the step 2, there is an error happened when execute the line 425, here is the console output:
