Building a query - SuperOffice

Select from

The 1st and mandatory part of the query is to set the columns and tables to fetch data from. You do this by adding 1 or more fields - optionally with a function to use on the field.

Make sure that all fields in a query start with the same table. Otherwise, you get a big join, which is probably not what you intended or need.

Void addField(String field)

Adds a field to the select-part of the query.

SearchEngine se;
se.addField("ticket.cust_id.firstname");

Void addField(String field, String func)

Adds a field to the select-part of the query and sets a function to use on that field. Functions are listed in the reference section at the end of this page. Use the function names in the left column for addField().

SearchEngine se;
se.addField("ticket.cust_id.firstname", "lower");

Void addFields(String table, String fields)

A shortcut for add multiple fields to a query. addFields() - notice the trailing s - it will add all fields in the comma-separated string fields, prefixed by the table name and a dot (.)

SearchEngine se;
se.addFields("ticket", "id,title,category.fullname,cust_id.fullName");

This single call to addFields() corresponds to the following 4 calls to addField():

SearchEngine se;
se.addField("ticket.id");
se.addField("ticket.title");
se.addField("ticket.category.fullname");
se.addField("ticket.cust_id.fullName");

Where

The 2nd and optional part of the query is to set conditions that the data must satisfy. If you have multiple criteria, you can group and order them by giving each a priority. All criteria with the same number will be placed inside the same brackets.

Void addCriteria(String field, String compOperator, String value)

This is the basic variant of addCriteria() and it’s often used when you need only 1 condition. It compares field to value using the operator. Comparison operators are listed in the reference section at the end of this page. Remember that the operator and value must correspond to and be appropriate for the field type. If the comparison evaluates to true and there are no other criteria or restrictions, the row is added to the search result. In other words, you restrict the inclusion of a row based on a field.

SearchEngine se;
se.addCriteria("associate.type", "OperatorEquals", "0");

Void addCriteria(String field, String compOperator, String value, String rowOperator, Integer priority)

This variant of addCriteria() extends the condition by also adding a priority and a logical operator. It is typically used when another criterion follows this one. Row operators are listed in the reference section at the end of this page.

SearchEngine se;
se.addCriteria("ticket.status", "OperatorEquals", "1", "OperatorAnd", 0);

Notice that the priority is a number and not a string.

Void addCriteria(String field, String function, String compOperator, String value, String rowOperator, Integer priority)

Same as above while also specifying a function to use on the field. Functions are listed in the reference section at the end of this page. Use the function names in the 2.nd column for addCriteria() - those starting with Func.

SearchEngine se;
se.addCriteria("ticket.status", "FuncCount", "OperatorEquals", "1", "OperatorAnd", 0);

Void addComparison(String field1, String compOperator, String field2, String rowOperator, Integer priority)

Similar to addCriteria(), but addComparison() will compare 2 fields to each other rather than compare a field to a set value.

Void addComparison(String field1, String func1, String compOperator, String field2, String func2, String rowOperator, Integer priority)

Same as above while also specifying a function to use on each field.

Void addJoinCriteria(String p0, String p1, String p2, String p3, Integer p4)

This method doesn’t work with NetServer. You need to bypass NetServer if you need to call addJoinCriteria(). Bypass is supported for onsite only.

Group by, having

The next (and optional) part of the query is to combine and filter the data. For example, you want to list how many customers you have in each country (combine) but ignore countries with less than 5 customers (filter).

Group by, having, and aggregate functions don’t work with NetServer. You need to bypass NetServer if you need to call setGroup() and addHaving(). Bypass is supported for onsite only.

Void setGroup(Bool set)

A group-by clause applies to all fields in the query - those added by calling addField(). This will combine all rows that have the same values into summary rows. It is often used with aggregate functions (count,avg,sum,max).

setGroup(true) set the group-by clause
setGroup(false)remove a group-by clause

SearchEngine se;
se.addField("sale.associate_id.name");
se.addField("sale.amount", "avg");
se.bypassNetServer(true);
se.setGroup(true);

Void addHaving(String field, String compOperator, String value, String rowOperator, Integer priority)

A having clause filters the search result by setting a condition similar to addCriteria(). The field you want to place a restriction on must also be in the group-by clause.

Void addHaving(String field, String func, String compOperator, String value, String rowOperator, Integer priority)

Same as above while also specifying a function to use the field. It is often used with aggregate functions (count,avg,sum,max) when you can’t apply those in the where clause.

SearchEngine se;
se.addField("sale.associate_id.name");
se.addField("sale.amount", "avg");
se.setGroup(true);
se.addHaving("sale.status", "OperatorEquals", "1", "OperatorAnd", 0);

Distinct, order by

The final (and optional) part of the query is to sort the data and/or remove duplicates.

Void addOrder(String field, Bool ascending)

Lists the result in ascending or descending order based on a field value.

SearchEngine se;
se.addFields("ticket", "status,id,title,created_at");
se.addCriteria("ticket.status", "OperatorEquals", "1", "OperatorAnd", 0);
se.addOrder("ticket.created_at", true);
printLine(se.executeTextTable());

Void addOrder(String field, String function, Bool ascending)

Lists the result in ascending or descending order based on the result from using function f on the field value.

Void setDBDistinct(Bool p0)

Forces SearchEngine to use DISTINCT in the query.

Requires NetServer to be bypassed. Not supported for CRM Online.

Void setDistinct(String field)

Sets which field you want to determine uniqueness based on.

SearchEngine se;
// ...
se.setDistinct("ticked.id");

In this example, identical tickets will not be listed. There will be exactly 1 entry with the same ticket ID. Very useful with many-to-many relations.

House-keeping

Integer select()

Runs the query and returns the size of the result set as an Integer.

Void setLimit(Integer number)

If you have a large database, it can be wise to restrict the amount of data you get back. setLimit() puts a cap on the number of rows you receive in the result set.

SearchEngine se;
// ...
se.setLimit(100);

String buildSql()

Returns the SQL query generated by the SearchEngine. This is only an estimate of the actual SQL because the query is sent to NetServer. Example:

select a0.status,a0.id,a0.title,a0.created_at from ticket a0 where (a0.status = ?) order by a0.id desc

String buildSql(String p0)

Same as above, but you can specify the type of query:

select
insert
update
delete

What’s next?

You now know how to build a SearchEngine query, look at the generated SQL, gauge the size of the search result, and limit it if need be. It is now time to turn to executing the query.

Reference

Functions

A function specifies what to do with the value of a field.

Function	Other name	Applies to	bypassNetServer	Description
avg	FuncAvg	Integer, Float	yes	aggregate, the average value of a column
count	FuncCount	Integer, Float	yes	aggregate, the number of rows matching cond.

max	FuncMax	Integer, Float	yes	aggregate, the largest value of a column
min	FuncMin	Time, DateTime
hour	FuncHour	Time, DateTime
wday	FuncWDay	Date, DateTime

Row operators

A row operator is a logical operator used to combine 2 criteria in a search condition.

Value	Logical operator	Expression	Result
OperatorAnd	AND	A && B	Only rows matching both conditions
OperatorNotAnd	NAND	!(A && B)	Rows matching 0 or 1 condition but not both
OperatorOr	OR	A \|\| B	Rows matching either condition (or both)
OperatorNotOr	NOR	!(A \|\| B)	Only rows matching no conditions

Comparison operators

A comparison operator evaluates the value of a field as part of a search condition. Notice that all operators are specified as strings in the argument list.

Value	Same as	Result
OperatorEquals	==	values match
OperatorNotEquals	!=	values don’t match
OperatorLt	<	value less than
OperatorLte	<=	value less than or equal
OperatorGt	>	value greater than
OperatorGte	>=	value greater than or equal
OperatorIs		values of the same type
OperatorIsNot		values of different types
OperatorLike		pattern found in string
OperatorNotLike		pattern not found in string
OperatorContains		string is present
OperatorBeginsWith		string starts with
OperatorEndsWith		string ends with
OperatorIn		column has entries in table
OperatorNotIn		column has no entries in table
