The application that is running this, or the connection thinger (ODBC, JDBC,
DBI) is parsing it twice. They often do a describe before a parse, which
results in two parses for every execution.
945 * 2 = 1895

Why should a query such as this, with bind variables and no literals,
be parsed so many times? Other queries in the trace show, for example,
2 parses and 160000 executions. And while I'm at it, why does is the
parse count shown equal to the SUM of executes and fetches?
SELECT BENEFICIARY_FK, BENEFICIARY_PHONE_PK, PHONE_TYPE_FK,
PHONE_NUMBER
FROM BENEFICIARY_PHONE WHERE COMPANY_FK = :V00001
AND BENEFICIARY_FK IN ( :V00002)
call count cpu elapsed disk query current
------- ------ -------- ---------- ---------- ---------- ----------
Parse 1890 0.21 0.17 0 0 0
Execute 945 0.04 0.08 0 0 0
Fetch 945 38.48 43.24 0 620428 0
