The qbe system converts the user input into a formal database query using structured query language (sql) on the backend, allowing the user to perform powerful searches without having to. The user information is kept in a separate system database, and access is controlled on each object in the system (for instance by table or by query). Sql statements also include the semicolon (;) statement terminator Though not required on every platform, it is defined as a standard part of the sql grammar Insignificant whitespace is generally ignored in sql statements and queries, making it easier to format sql code for readability. It is part of the microsoft 365 suite of applications, included in the professional and higher editions or sold separately
Microsoft access stores data in its own format based on the access database. The sql select statement returns a result set of rows, from one or more tables [1][2] a select statement retrieves zero or more rows from one or more database tables or database views In most applications, select is the most commonly used data manipulation language (dml) command As sql is a declarative programming language, select queries specify a result set, but do not specify how to. A query language, also known as data query language or database query language (dql), is a computer language used to make queries in databases and information systems
[1] a well known example is the structured query language (sql). The set of query plans examined is formed by examining the possible access paths (e.g., primary index access, secondary index access, full file scan) and various relational table join techniques (e.g., merge join, hash join, product join) The search space can become quite large depending on the complexity of the sql query.
