Other mitigating factors come into play specifically, the local PC’s installed Oracle client version(s) (covered later in this chapter) and Toad’s data access component, which communicates to the database via that client. However, Figure 1.1 does not answer the compatibility question. In fact, Toad 10.1 supports Oracle 11g R2, whereas Toad 12.1 supports Oracle 12c (i.e., 12.1.0.1). In general, Toad support for new database version features will be either the first or second Toad release after the database release. Because Toad 9.7 was released before either of those Oracle versions, such users won’t be able to use Toad to leverage 11g R2 or 12c features. However, the same people also tend to be using Oracle 11g R2 or 12c. So, for example, a fair number of people are still using Toad 9.7, mostly because they did not pay for maintenance (that is, support) and thus were not entitled to updates. If the Toad release precedes the Oracle release in question, then obviously there’s no way that version of Toad can support the new database features. Note that Figure 1.1 entirely answers the support question. You can learn a lot from this diagram.įIGURE 1 Toad and Oracle release histories Figure 1.1 shows the history timeline for both products’ versions. Then there’s what version of Toad supports which Oracle database version’s new features-that is, support. Knowing what version of Toad works with which version(s) of the Oracle database is one example - that is, compatibility. Some important interdependencies exist among all of those releases. Thus began its commercial journey.ĭuring those two decades there have been many Toad, as well as Oracle, database releases. Around 1997 Toad and that developer were acquired by Quest Software (now Dell Software). It started as freeware built by one lone Oracle user who hated using the command line in SQL*Plus - and no graphical tools were available. Toad has been around for almost two decades.
