ODBC SQLBindParameter for string array

[Andre]

Hi,

I have some issues with the ODBC SQLBindParameter. I already
achieved to add an array of integers but the scenario of writting
a string array is not working.
While doing the INSERT statement 3 rows are added to the
database. The first row has the correct value "A". The second row
has not value instead of "B". And the third row has a strange
value and the character 'P' instead of "C".

Do you have some idea?

Kind regards
André

// CREATE TABLE demo(name VARCHAR(1))
// INSERT INTO demo (name) VALUES (?)

string[] stringArr = ["A","B","C"];

SQLSetStmtAttr(hStmt, SQL_ATTR_PARAMSET_SIZE,
   cast(SQLPOINTER) stringArr.length, 0);
SQLSetStmtAttr(hStmt, SQL_ATTR_PARAM_BIND_TYPE,  cast(SQLPOINTER)
   SQL_PARAM_BIND_BY_COLUMN, 0);
SQLINTEGER[] lengIndArr = new SQLINTEGER[](table.rowCount);

// Get max length, in this example always: 1
int maxLength = 0;
foreach(str;stringArr){
   if(str.length > maxLength){
     maxLength = str.length;
   }
}

// SQLCHAR is defined as ubyte
SQLCHAR[][] charArr = new SQLCHAR[][](stringArr.length, maxLength
+ 1);
// +1 for \0 character

foreach(i, str;stringArr){
   charArr[i] =   cast(SQLCHAR[]) (str~"\0");
   lengIndArr[i] = SQL_NTS; // Null terminated string
}

SQLBindParameter( hStmt, cast(SQLUSMALLINT) 1, cast(SQLSMALLINT)
   SQL_PARAM_INPUT, cast(SQLSMALLINT)SQL_C_CHAR,
cast(SQLSMALLINT)SQL_VARCHAR,
   maxLength, 0, charArr[0].ptr , maxLength + 1, lengIndArr.ptr);
