.SH "NAME"
tinysparql-sql \- Use SQL to query the TinySPARQL databases\&.
.SH "SYNOPSIS"
.sp
.nf
tinysparql sql \-q <sql> | \-f <file>
.fi
.SH "DESCRIPTION"
.sp
This command allows probing of the current database\&. When using commands like \fBtinysparql sparql\fR, the SPARQL used is translated into SQL before being run on the database\&. This allows direct use of the database using SQL avoiding the SPARQL engine entirely\&.
.sp
The caller can run a query two ways, either by providing a \fIfile\fR with the query or by providing a string with the \fIsql\fR query\&.
.sp
The \fIfile\fR argument can be either a local path or a URI\&. It also does not have to be an absolute path\&.
.SH "OPTIONS"
.PP
\fB\-f, \-\-file=<\fR\fB\fIfile\fR\fR\fB>\fR
.RS 4
Use a
\fIfile\fR
with SPARQL content to query\&. Don\(cqt forget to end all queries with a semicolon (;) and also to use quotes around table names\&. The quotes are important because most tables are named after ontology classes like "nfo:Document" and queries will fail without the quotes\&.

.PP
\fB\-q, \-\-query=<\fR\fB\fIsql\fR\fR\fB>\fR
.RS 4
Use a
\fIsql\fR
string to query the database with\&.
