Hello
I have a problem using PostgreSQL with pyqt. My pc is a Windows 7 32bit,
i've installed postgresql 9.1 with odbc drivers BUT i want to use it in
pyqt with the native driver. I've wrote a small script to test everything
but this work if i use ODBC, if i use PSQL i get an errore "Driver not
loaded".
This is the code:
app = QCoreApplication(sys.argv)
db = QSqlDatabase.addDatabase("QPSQL")
db.setHostName('localhost')
db.setPort(5432)
db.setDatabaseName('TestDB')
db.setUserName('postgres')
db.setPassword('*****')
if db.isOpen():
db.close()
if not db.open():
raise Exception("Error opening database:
{0}".format(db.lastError().text()))
query = QSqlQuery()
query.exec_("select * from test_table;")
while query.next():
print(query.value(0), query.value(1) )
This code return the error "Driver not loaded". If i change only the
database driver, this line:
db = QSqlDatabase.addDatabase("QODBC")
I get the correct output:
1 Prova paolo
2 Prova Pippo Baudo
So what's wrong ?
I've cheked qsqlpsql4.dll with dependecy walker and i get this log:
Error: At least one required implicit or forwarded dependency was not
found.
Error: At least one module has an unresolved import due to a missing
export function in an implicitly dependent module.
Warning: At least one module has an unresolved import due to a missing
export function in a delay-load dependent module.
The missing librery should be MSVCR90.DLL but even if i dowload this file
from internet i get the same error.
I've tryed to install Microsoft Visual C++ 2010 runtime (vcredist_x86.exe)
with no success.
