The following expression converts the constant 500 to type Decimal in order to compare it to a Transact-SQL money data type in theValuefield for a filter expression: basic =CDec(500) The following expression displays the number of values selected for the multivalue parameterMySelection: ...
Anameofexpression produces the name of a variable, type, or member as the string constant. Anameofexpression is evaluated at compile time and has no effect at run time. When the operand is a type or a namespace, the produced name isn'tfully qualified. The following example shows the use...
When programming or using application language, you'll also encounter Boolean expressions. A Boolean expression is an expression that results in a Boolean value and, for that, you can use a Boolean variable or constant. Typically, relational and logical expressions evaluate in Boolean values....
Ifdata_nameis a matrix, the operator returnstruewhen it detects a change in any element ofdata_name. Index elements of a matrix by using numbers or expressions that evaluate to a constant integer. SeeOperations for Vectors and Matrices in Stateflow. ...
During optimization of the SELECT statement in the procedure, the optimizer tries to evaluate the expected cardinality of the result set for the condition OrderDate >@d+1. The expression@d+1is not constant-folded, because@dis a parameter. However, at optimization time, the value of the parame...
Mapping cell type-specific gene expression quantitative trait loci (ct-eQTLs) is a powerful way to investigate the genetic basis of complex traits. A popular method for ct-eQTL mapping is to assess the interaction between the genotype of a genetic locus
