Try this:
// SQLCHAR is defined as ubyte
SQLCHAR*[] charArr = new SQLCHAR*[](stringArr.length);
foreach(i, str;stringArr){
charArr[i] = cast(SQLCHAR*) toStringz(str); // import std.string
lengIndArr[i] = SQL_NTS; // Null terminated string
}
The SQL API is expecting an array of (C) char* pointers, not an array of
D's ubyte[] (which is actually twice the size).
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, // I don't think the +1 is necessary..
lengIndArr.ptr);
