Hi,
Found the issue in ocilib code.
In your example, with current versions of OCILIB, OCI_GetVersionConnection() should return 90200 instead of 920 for a Oracle 9.2.0 server version.
In v4.7.5, I changed the version integer values returned by OCI_GetVersionConnection() to be on 6 digits instead of 4 to handle the minor and rev number on more than 1 digits.
When using oracle 18+, ver_maj, ver_min and ver_rev are retrieved from oracle OCI APIs and then assembled into a single integer value on 6 digits and OCI_GetVersionConnection() returns a correct integer value.
By for previous Oracle version, the version is computed by parsing the server banner (same as the one shown in SQL*PLUS).
And the extracted ver_maj, ver_min and ver_rev are not assembled using the new 6 digit scheme introduced in v4.7.5 but with the old scheme on 4 digits.
As OCI_GetServerMajorVersion, OCI_GetServerMinorVersion and OCI_GetServerRevisionVersion are extracting their value from the combined 6 digits integer value, in case the server is pre 18, they are parsing a 4 digits integer value and then lead to the erroneous value you've seen.
It will be fixed in the current 4.7.7 dev branch by the end of the day :)
