I have a Python script that uses the psycopg2 library to connect to Postgres and copy tables from the a Postgres database to text files (tab-separated). This works perfectly. I'm then trying to run a similar function, but this time taking the text files and inserting them into an identical table in a different Postgres database. My script is as follows:
def copyFromFile(tableName):
try:
cTo = None
cTo = psycopg2.connect(database="postgres", user="postgres", password="postgres", host="localhost")
tCursor = cTo.cursor()
print 'here'
io = open(tableName+'.txt', 'r')
tCursor.copy_from(io, tableName)
print 'done copying'
except Exception as inst:
print "I am unable to copy to " + tableName
#start
copyFromFile('schema.tableName')
The text file looks like this:
95216 8802 269726 3 1350 1 2014-09-02 14:11:25.817178 I
95217 8802 269726 4 1351 1 2014-09-02 14:11:25.817178 I
95218 8802 269726 5 1352 1 2014-09-02 14:11:25.817178 I
95219 8802 269726 6 1353 1 2014-09-02 14:11:25.817178 I
95220 8802 269726 7 1354 1 2014-09-02 14:11:25.817178 I
95221 8802 269726 8 1355 1 2014-09-02 14:11:25.817178 I
95222 8802 269726 9 1356 1 2014-09-02 14:11:25.817178 I
When I run this script, I get no errors, but the database table gets no data. This table is empty to start with. What could be missing?
print 'done copying'
cTo.commit()
maybe? -g
