hello
I am trying to get count(column ) to variable from database in server script
If there is no data in table error message showing to me

how I can check if there is no data in table I will make my variable equal 1

my code

parentaccount=doc.parent_account
lastinsertedaccountdate = frappe.db.sql("""
        SELECT  count(creation) FROM `tabAccount`
        WHERE parent_account = %s 
    """, parentaccount)[0][0] or 0

error message is
pymysql.err.DataError: (1264, “Out of range value for column ‘intcol’ at row 1”)

@Hamza_Erpnext try this
parentaccount = doc.parent_account
query_result = frappe.db.sql(“”"
SELECT COUNT(creation) FROM tabAccount
WHERE parent_account = %s
“”", parentaccount)
if query_result and query_result[0][0] is not None:
lastinsertedaccountdate = query_result[0][0]
else:
lastinsertedaccountdate = 1
