After the aggregating operation, HAVING is applied, filtering out the rows that don't match the specified conditions. Therefore, WHERE applies to data read from tables, and HAVING should only apply to aggregated data, which isn't known in the initial stage of a query. To view the present condition formed by the GROUP BY clause, the HAVING ...
Tamil being a strongly head-final language, the basic word-order is SOV. However, since it is highly inflected, word order is flexible and is used for pragmatic purposes. That is, fronting a word in a sentence adds emphasis on it; for instance, a VSO order would indicate greater emphasis on the verb, the action, than on the subject or the object.
In linguistic typology, the object–subject–verb (OSV) or object–agent–verb (OAV) word order is a structure where the object of a sentence precedes both the subject and the verb. Although this word order is rarely found as the default in most languages, it does occur as the unmarked or neutral order in a few Amazonian languages ...
Because it acts on the results of the GROUP BY clause, aggregation functions can be used in the HAVING clause predicate. The ORDER BY clause identifies which column[s] to use to sort the resulting data, and in which direction to sort them (ascending or descending). Without an ORDER BY clause, the order of rows returned by an SQL query is undefined.
For example, Russian has a relatively fixed SVO (Subject-Verb-Object) word order in transitive clauses, but a much freer SV / VS order in intransitive clauses. [ citation needed ] Cases like this can be addressed by encoding transitive and intransitive clauses separately, with the symbol "S" being restricted to the argument of an intransitive ...
They have SOV in subordinate clauses, as given in Example 1 below. Example 2 shows the effect of verb second order: the first element in the clause that comes before the V need not be the subject. In Kashmiri, the word order in embedded clauses is conditioned by the category of the subordinating conjunction, as in Example 3.
Unlike English, which places a relative clause (RC) after the head noun that it modifies, Cantonese is very unusual among SVO languages by placing relative clauses before head nouns and by having prenominal relative clauses, which cause a VOS word order, as is seen in most subject-gapped relative clauses.

SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
