Hi, I tried to getting the count of some filegeodatabase rows with "File Geodatabase API 1.4", but the performance is very poor as following statements:
| The Source code |
|---|
Geodatabase geodatabase = Geodatabase.Open(@"xxxxxx"); var countStatements = $"SELECT count(*) FROM blk WHERE OBJECTID=1 or OBJECTID=2";
var countRows = geodatabase.ExecuteSQL(countStatements); var countEnumerator = countRows.GetEnumerator(); if(countRows != null)
{
countEnumerator.MoveNext();
count = (int)countEnumerator.Current.GetDouble(0);
} |
It took about two seconds to getting the result. The performance is very poor!
How can I promote the performance through query sql statements or the other approach?
I’m very appreciate for your any help.
I have posted it to the File GeoDatabase API discuss : How to promote the performance on querying filegeodatabase entries count??
Thanks,
Casper. Lee
