How to Convert to String Search In Sparql?

In SPARQL, you can convert a search query to a string by using the STR() function. This function takes a variable or an expression as input and returns a string representation of that value.

For example, if you have a search query that looks for a specific property value, you can convert that value to a string using the STR() function. This can be useful if you need to pass the search query as a parameter to another function or if you want to manipulate the search query as a string.

Overall, converting a search query to a string in SPARQL can be done easily using the STR() function, allowing you to work with the search query as a string data type.

What is the syntax for converting to string in SPARQL?

The syntax for converting a value to a string in SPARQL is by using the STR() function.

Example:

1
2
3
4
5

SELECT ?name (STR(?age) AS ?ageString)
WHERE {
  ?person foaf:name ?name ;
          ex:age ?age .
}

In the example above, the STR() function is used to convert the value of the ?age variable to a string and assign it to a new variable called ?ageString.

How to convert blank node to string in SPARQL?

1
2
3

SELECT (STR(?blankNode) AS ?string) WHERE { 
   ?subject ?predicate ?blankNode . 
}

In this query, STR() function is used to convert the ?blankNode to a string and assign it to a new variable ?string. This will give you the string representation of the blank node in the query results.

How to convert datetime to string in SPARQL?

In SPARQL, you can convert a datetime to a string using the STR function. Here is an example query that demonstrates how to convert a datetime to a string:

1
2
3
4
5
6

PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>

SELECT ?stringDate
WHERE {
  BIND(STR(xsd:dateTime("2022-03-15T12:00:00")) AS ?stringDate)
}

In this query, we use the STR function to convert the datetime value "2022-03-15T12:00:00" to a string. The result of this query will be a string representation of the datetime value. You can replace the datetime value in the query with the datetime value you want to convert to a string.
