large amounts of comma-separated value content. The CSV virtual table is also useful as a template source file for implementing other virtual tables. </p> <p> The CVS virtual table is not built into the SQLite amalgamation. It is available as a [https://www.sqlite.org/src/artifact?ci=trunk&filename=ext/misc/csv.c|separate source file] that can be compiled into a [loadable extension]. Typical usage of the CSV virtual table from the [command-line shell] would be something like this: <codeblock> ................................................................................ <li><p><b>data=</b><i>TEXT</i> <p>The <b>data=</b> argument specifies that <i>TEXT</i> is the literal content of the CSV file. <li><p><b>schema=</b><i>SCHEMA</i> <p> The <b>schema=</b> argument specifies a [CREATE TABLE] statement that the CVS virtual table passes to the [sqlite3_declare_vtab()] interface in order to define the number and names of the columns in the virtual table. If both the <b>schema=</b> and the <b>columns=</b> arguments are omitted, then the CVS virtual table reads the first row of the input content in order to determine the number of columns and names the columns <b>cNNN</b> where <b>NNN</b> values are consecutive integers. It is not allowed to have both <b>schema=</b> and <b>columns=</b> arguments. <li><p><b>columns=</b><i>N</i> <p>The <b>columns=</b><i>N</i> argument causes the virtual table to have exactly <i>N</i> columns. If the input data contains more columns than this, then the excess columns are ignored. If the input data contains fewer columns, then extra columns are filled with NULL. </u> |
