GroceryCrud with SQL Server (primarykey issue) - php

Question

I try to use GroceryCRUD with SQL Server (2008 R2) to manage some table.
Well, I find the following thread very usefull on StackOverflow :
How can I run grocery with sql server?
But, when I use $this->grocery_crud->set_relation, it returns an error "PrimaryKey not found" on the method set_primary_key.
The table obviously has correctly set the primary key.
Can someone help me figure out where is the problem?

Answer 1

Ok. This is how I hack the code:
ref.version:
grocery-crud-1.5.2
CodeIgniter-3.0.1
STEP 1
File: system\database\drivers\pdo\subdrivers\pdo_sqlsrv_driver.php
Update method field_data($table)
public function field_data($table)
{
$sql = 'SELECT c.COLUMN_NAME, c.DATA_TYPE, c.CHARACTER_MAXIMUM_LENGTH, c.NUMERIC_PRECISION, c.COLUMN_DEFAULT
,CASE WHEN pk.COLUMN_NAME IS NOT NULL THEN 1 ELSE 0 END AS KeyType
FROM INFORMATION_SCHEMA.COLUMNS c
LEFT JOIN (
SELECT ku.TABLE_CATALOG,ku.TABLE_SCHEMA,ku.TABLE_NAME,ku.COLUMN_NAME
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS tc
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS ku
ON tc.CONSTRAINT_TYPE = \'PRIMARY KEY\'
AND tc.CONSTRAINT_NAME = ku.CONSTRAINT_NAME
) pk
ON c.TABLE_CATALOG = pk.TABLE_CATALOG
AND c.TABLE_SCHEMA = pk.TABLE_SCHEMA
AND c.TABLE_NAME = pk.TABLE_NAME
AND c.COLUMN_NAME = pk.COLUMN_NAME
WHERE UPPER(c.TABLE_NAME) = '.$this->escape(strtoupper($table));
if (($query = $this->query($sql)) === FALSE)
{
return FALSE;
}
$query = $query->result_object();
$retval = array();
for ($i = 0, $c = count($query); $i < $c; $i++)
{
$retval[$i] = new stdClass();
$retval[$i]->name = $query[$i]->COLUMN_NAME;
$retval[$i]->type = $query[$i]->DATA_TYPE;
$retval[$i]->max_length = ($query[$i]->CHARACTER_MAXIMUM_LENGTH > 0) ? $query[$i]->CHARACTER_MAXIMUM_LENGTH : $query[$i]->NUMERIC_PRECISION;
$retval[$i]->primary_key = $query[$i]->KeyType;
$retval[$i]->default = $query[$i]->COLUMN_DEFAULT;
}
return $retval;
}

}
STEP 3
File: \system\database\drivers\mssql\mssql_result.php
Update method field_data()
public function field_data()
{
$retval = array();
for ($i = 0, $c = $this->num_fields(); $i < $c; $i++)
{
$field = mssql_fetch_field($this->result_id, $i);
$retval[$i] = new stdClass();
$retval[$i]->name = $field->name;
$retval[$i]->type = $field->type;
$retval[$i]->max_length = $field->max_length;
$retval[$i]->primary_key = $field->primary_key;
}
return $retval;
}
That's all. I hope it can help other people.
