notLike

notLike(X, pattern)

X is a STRING scalar/vector.

pattern is a string, usually containing wildcards (e.g., "%").

This function checks whether X does not match the pattern specified by pattern. The comparison is case-sensitive.

Return value: A Boolean scalar or vector.

notLike(`DEFG, `DE);
// output: true

notLike(`DEFG, "%DE%");
// output: false


a=`IBM`ibm`MSFT`Goog;
notLike(a, "%OO%");
// output: [true,true,true,true]

print a[notLike(a, "%OO%")];
// output: ["IBM","ibm","MSFT","Goog"]

notLike can be used with SQL SELECT to exclude records matching certain conditions:

t = table(`abb`aac`aaa as sym, 1.8 2.3 3.7 as price);
select * from t where sym notLike "%aa%";

notLikecan also be applied to queries on DFS tables:

dbName="dfs://database1"
if(existsDatabase(dbName)){
	dropDatabase(dbName)
}
db=database(dbName,VALUE,2019.01.01..2019.01.03)
n=100
datetime=take(2019.01.01 +0..100,n)
sym = take(`C`MS`MS`MS`IBM`IBM`IBM`C`C$SYMBOL,n)
price= take(49.6 29.46 29.52 30.02 174.97 175.23 50.76 50.32 51.29,n)
qty = take(2200 1900 2100 3200 6800 5400 1300 2500 8800,n)
t=table(datetime, sym, price, qty)
trades=db.createPartitionedTable(t,`trades,`datetime).append!(t)

select * from trades where sym notLike "%IBM%"
